A technology magazine reportat that 18% of households in a city have switched to fiber-optic internet. Suppose a sample of 250 households is collected to determine whether the rate of switching to fiber-optic intedrnet has decreased. Formulate the hypotheses that can be used to determine whether the rate of switching to fiber-optic intedrnet has decreased. Ho: p>0.18, Ha: p<=0.18 If the sample results show that 35 of the households have switched to fiber-optic internet, find the value of the test statistic. If the sample results show that 35 of the households have switched to fiber-optic internet, find the p-value. At alpha=0.05, what is your conclusion
